To all whom it may concern.-

Be it known that I, GUSTAVE A. PFonT KER, a citizen of the United States, residing at borough of the Bronx, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Smoking Devices, of which the following is a specification, reference being had therein to the accompanying draw- I,

- for cleaning or substitution of new parts and snugly into the rear 'end of the shank 11.

a pipe.

smoke-conduit.

ease of cleaning of parts.

I will now describe the smoking devices embodying my invention illustrated in the accompanying drawings and will thereafter point out my invention in claims.

Figure 1 is a longitudinal central section of Fig. 2 is a detail elevation of the inner tube of the smoke-conduit. Fig. 3 is a detail longitudinal section of the cup of the Fig. 4 is a detail longitudinal section of the outer tube of the smokeconduit. Fig. 5 is a transverse section taken through the pipe stem on a plane indicated by the line 55, Fig. 1. Fig. 6 is a longitudinal central section of a cigar-holder, of modified construction. Fig. 7 is a detail elevation of the inner tube/"Fig. 8 is a detail longitudinal section of the on and Fig. 9 is a detail longitudinal section 0 the outertube 0f the smoke-conduit of such modified construction.

The pipe shown in Fig. 1 has a bowl 10 and has a stem madeup of two parts, one of which is the shank 11 of the bowl member and the other the mouth-piece12, the mouthpiece beingsecured to the shank by a frictional' joint comprising a reduced portion 13 at the front end of the mouth-piece fitting Thestem shown is a straight stem and the parts aredescribed as with the stem in the chamber 14 formed therein and the reduced front end of the mouth-piece 12 enters this chamber, and this chamber extends from the mouth-piece 12 to within a short distance of the bowl 10, and is connected with the bowl 10 by a short bore or smoke-passage 9. The mouth-piece 12 is provided with the usual bore or smoke-passage l5 and has a threaded stud 16 at its front end over which is screwed the outer tube 17 of a smoke-conduit comprising a plurality of tubular parts of different diameters forming a plurality of revcrsely arranged outer tube 17 of the smoke-conduit is provided at its front end with an internal thread into which is screwed a threaded portion 19 on the enlarged front end of the inner tube 18 of the smoke-conduit, a shoulder 8 being provided on the extreme front end of this enlarged portion of the inner smoke-tube to abut against the front end of the outer tube 17 and make a tight joint and also to afford a grip for unscrewing the parts. i In the construction shown in Figs. 1 to 5, inclusive, the inner tube 18 of the smoke-conduit is also provided with another enlarged threaded portion 20 of smaller diameter than the threaded portion 19, and upon this second threaded portion 19 is screwed an intermediate .tubular ortion 21 which has a closed rear end an which I shall denominate a cup. The inner tube of the smoke-conduit is enveloped 'on its sides and at its rear end by the cup 21, but with a sufficient annular and rear end space between the cup and inner tube for the passage of smoke. The cup 21 is provided in proximity to its front end with suitable apertures 22 which permit flow of smoke tlierethrough from the annular passage between the inner tube 18 and cup 21 to an annular assage between the cu 21 and the outer tu e 17. The rear end 0 the cu 21 terminates at a sufficient distance in a vance of the front end of the mouth-piece to permit the flow of smoke from the annular passage between the cup 21 and the outer tube 17, to the smoke-passage 15 of the mouth-- smoke passages. This the smoke is com I nular passage between the cup 21 and the outer tube 17, before it enters the smokepassage of the mouth-piece. The outer tube 17 of the'smoke-conduit is of smaller diameter than the inner periphery of the wall of the chamber 14 so that there is a longitudinal and annularspace between the smoke-con duit and the wall of the chamber, and the front end of the smoke-conduit terminates inrear ofthe front wall of'the chamber 14 so that here. also there is a clearance space of substantially the full diameter of the chamber 14. One of the consequences of this construction is that an liquid which may possibly flow forward t ou h the inner tube 18 would not flow into the W1, but would be trapped in'the chamber 14. Another consequence of this construction is that the outer wall of the chamber is separated by an air space from all parts in whic the smoke is circulated and therefore the shank 11 remains comparatively cool. This latter result is accentuated by providing an air-inlet leadin into the chamber 14, this air-inlet 23 being ormed in the shank 11 near the rear end thereof, so that cold air may enter the annular space about the smoke-conduit, cooling both surfaces with which it flows in contact and finally mixing with and cooling the smoke entering the smoke-conduit. The cooling action of the inflowin cold air may be ma c more effective by emp oyin a metal, such as aluminium, as the materia of which i the smoke-conduit is partly or wholly made,

particularly the outer tube 17.

' The cigar-holder shown in Figs. 6, 7, 8 and 9, is of a slightl modified construction in that the inner tube 27 of the smoke-conduit has only one threaded portion 28, and the cup is screwed thereon. Here also the cup is made of two parts, a tubular portion 24- and a removable closure or. plug 25, this plug 25 being screwed into the rear end of the tubular portion 24. The front end of the tubular portion 24 of the cup is screwed over the enlarged threaded part of the inner smoketube 27, as above described, and is also externally threaded so that the front'end of the outer tube 29 of the smoke-conduit may be screwed over it. A shoulder 26 acts as an abutment both for the cup and the outer tube.

' The outer tube 29 is here partly closed at its openin into the space between the outer tube 0 the, smoke-conduit and the wall of the chamber is omitted, but this space nevertheless performs its heat insulating function.

It wi I be noted that the several parts may be readily separated for cleaning and may be readily thoroughly cleaned, the manipus lations for separatingand assembling the construction shown and above particularly described within the principle and scope of my invention.

What I claim as new and desire to secure by Letters Patent, is:'
